CLAMP ON PROBE 3273-501

High S/N characteristics enable the measurement of,br>10 mA order current waveforms Wideband Current Probe for Oscilloscopes
Exclusive Academic Offer

Hioki flat bandwidth current probes are best-in-class current sensors
for use with Memory HiCorders and high performance oscilloscopes. The
3273-50 offers a wide DC to 50 MHz bandwidth and 30A of continuous
input, and is ideal for capturing transient current signals from
switching power supplies, inverters, and motor controllers.

Model No. (Order Code)

3273-50DC to 50 MHz, 30 Arms
CEDC

Note: Use the Power Supply 3269/3272 for
general measurements or when power is not
available from the Memory Hicorder.
When performing continuous measurements,
be aware of offset voltage drift.

Key Features

• Waveform observation across a wide band from DC to MHz
• Connects directly to oscilloscope or Memory HiCorder BNC input terminal *1
• High S/N characteristics enable the measurement of 10 mA order current waveforms (3273-50, 3276)

*1 Connecting the device’s metal BNC terminal to a Memory HiCorder’s plastic BNC terminal may damage the plastic terminal or cause it to become misshapen.
